What is the best practice for passing an object between PHP files without encountering errors like "Undefined variable" or "Trying to get property of non-object"?

When passing an object between PHP files, it is best practice to use sessions or serialization to ensure that the object retains its properties and values. This helps to prevent errors like "Undefined variable" or "Trying to get property of non-object" when accessing the object in the receiving file. 

// Sending file
session_start();
$_SESSION['myObject'] = serialize($myObject);

// Receiving file
session_start();
$myObject = unserialize($_SESSION['myObject']);
